Even though she made her first comeback appearance the other night at the Bambi Awards, people are clamoring to see even more of Britney Spears performing ‘Womanizer’ on stage. This time, Britney blew the crowd and judges away when she made a guest appearance on Simon Cowell’s 'X Factor' and now the video has gone viral.

Though the ‘Womanizer’ routine stayed the same, Brit did alter her clothing style and opted to ditch the top hat and also wore a pretty blouse over top of a black leotard.

An aside, Simon Cowell looked devilishly handsome!
